Comment #6 on issue 3349 by address@hidden: missing duration in  
\displayLilyMusic after a triplet
http://code.google.com/p/lilypond/issues/detail?id=3349

Hey people, this is on countdown.  Let me point out that the code contains  
the comment
;; would it be better to just clear previous-duration before
;; and afterwards, forcing explicit durations?

With this patch,
\displayLilyMusic { c'8 c' \tuplet 3/2 { c' c' c' } \tuplet 3/2 { c' c' c'  
} c' c' }
shows c'8 c' \tuplet 3/2 { c' c' c' } \tuplet 3/2 { c' c' c' } c' c' }
which I am not sure is a good idea.  The proposal to just kill durations  
before and after would result in
c'8 c' \tuplet 3/2 { c'8 c' c' } \tuplet 3/2 { c'8 c' c' } c'8 c' }
instead.  Another option would be to reset durations only on scale factor  
changes, resulting in
c'8 c' \tuplet 3/2 { c'8 c' c' } \tuplet 3/2 { c' c' c' } c'8 c' }
Codewise, just resetting durations before and after is easiest.  Since the  
scale factor is actually indistinguishable for \tuplet 3/2, \tuplet 6/4,  
and even \times 4/6, I lean towards just doing that in order to get  
reasonably clear results.

Opinions?
